If they move at the same speed than heavy one will have more inertia.
For the reaction;
N2(g) + O2(g) = 2NO(g)
Kp = pNO²/ pN₂pO₂; (No units)
where;
pNO is the partial pressure of NO;
pN₂ is the partial pressure of nitrogen
pO₂ is the partial pressure of Oxygen
The equilibrium constant Kp is deduced from the balanced chemical equation for a reversible reaction, NOT experimental data as is the case for rate expressions in kinetics.
Kp changes with temperature considerably changing the position of an equilibrium, and, at a constant temperature, and therefore constant K, the position of an equilibrium can change significantly depending on relative concentrations/pressures of 'reactants' and 'products'.
statement about enzymes that is correct is
b. they are large molecules that increase the rate of biologically important reactions
Enzymes are proteins that catalyse, in other words increase the rate of the biological reactions.
Biological functions that are vital for the bodies to survive, have large activation energy barriers. For this reason enzymes are used that reduce the activation energy required for the reaction to initiate. this enables the reactions to proceed.
Substrates bind to the enzyme, reaction occurs and substrate converts to products, that are released from the enzyme, leaving the enzyme unchanged.
so the correct answer is B.
Answer:
d = 14.9 g/mL
Explanation:
Given data:
Mass of metal = 22.4 g
Volume of eater = 3.2 mL
Volume of water + metal = 4.7 mL
Density of metal = ?
Solution:
Volume of metal:
Volume of metal = volume of water+ metal - volume of water
Volume of metal = 4.7 mL - 3.2 mL
Volume of metal = 1.5 mL
Density of metal:
d = m/v
d = density
m = mass
v = volume
d = 22.4 g/ 1.5 mL
d = 14.9 g/mL
